In the Linux kernel, the following vulnerability has been resolved: serial:
8250: omap: Don’t skip resource freeing if pm_runtime_resume_and_get()
failed Returning an error code from .remove() makes the driver core emit
the little helpful error message: remove callback returned a non-zero
value. This will be ignored. and then remove the device anyhow. So all
resources that were not freed are leaked in this case. Skipping
serial8250_unregister_port() has the potential to keep enough of the UART
around to trigger a use-after-free. So replace the error return (and with
it the little helpful error message) by a more useful error message and
continue to cleanup.
